Sound with some programs but none with others?

Moses420ca · 12-23-2006, 10:51 PM

I'm using OpenSuse 10.1 on a Dell Inspiron 640m laptop. The sound works for xmms, mpg123, mplayer, vlc, stuff that can use alsa I guess... The sound in Neverwinter Nights works but the sound in Quake3 does not. The sound doesn't work in KDE, firefox (flash), amsn, play (sox)... I've made it to kcontrol -> Sound.. no luck. tried alsaconf... Yast -> hardware -> Sound... no dice.

Not sure what to do here...
Thanks,
Drew

snippet from quake3 output:

------- sound initialization -------
Could not mmap dma buffer PROT_WRITE|PROT_READ
trying mmap PROT_WRITE (with associated better compatibility / less performance code)
/dev/dsp: Input/output error
Could not mmap /dev/dsp

Quote from ALSA FAQ:

Quote:

Q: The driver is loaded, but OSS programs say: Can't open /dev/dsp.
What is wrong?
A: The OSS compatible PCM (digital audio) emulation comes as an add-on module
which is not loaded by default. If you have got modified /etc/conf.module
as suggested in the INSTALL file, it should be loaded with kerneld or kmod.
Check it - if this method for some reason doesn't work - you need to insert
the 'snd-pcm-oss' module manually.

So, load appropriate module.

In my Debian Sarge it's snd_psm_oss.

I have that module loaded already but thanks... good idea.

Sound is working software:
program - driver - info
-xmms - alsa - hw:0,0
-xmms - oss - /dev/dsp and /dev/mixer
-mplayer - alsa - hw=0.0
-mplayer - oss - /dev/dsp and /dev/mixer
-xine - alsa - plug:front:default
-xine - oss - ?

Sound is NOT working software:
program - driver - error message
-Helix Banshee - helix remote and Gstreamer 0.10 - no error
-Amarok - helix and xine - general error message
-RealPlayer - ? - Can not open audio device
-firefox - youtube, flash... - no error

Interesting.

But, I have a bunch of oss emulation modules loaded:

Code:

lsmod |grep oss

snd_pcm_oss            48168  0 
snd_mixer_oss          16640  1 snd_pcm_oss
snd_pcm                85384  2 snd_intel8x0,snd_pcm_oss
snd_seq_oss            29440  0 
snd_seq_midi_event      7552  2 snd_seq_oss,snd_seq_midi
snd_seq_device          7944  3 snd_seq_oss,snd_seq_midi,snd_rawmidi
snd_seq                46480  5 snd_seq_oss,snd_seq_midi,snd_seq_midi_event
snd                    50660  15

For my integrated sound in Nvidia Nforce2.

And one more question:

In syslog, or dmesg output, do you see any errors, related to soundcard?
